In the US, "nonprofit" hospital chains cheat poor patients, demanding they pay even when state law says they don't have to, and sending debt collectors after them.

I suspect that mergers and competition for mergers are part of what turns formerly altruistic organizations greedy. Competition with for-profit companies may be part of it true.

I propose that states pass laws to prohibit mergers of organizations that provide medical care, and to prohibit for-profit companies from doing that. They should never have existed; let's get rid of them.
